The US National Ultra Endurance Series 2010 (NUE) sponsored by Kenda, will begin on April 24, 2010. 2009 NUE series champs were Betsy Shrogen and Jeff Schalk. The 100-mile mountain bike races will kick off at Cohutta 100 in Tennessee. The series is composed of eight 100 mile races and will end on September 5 at the Shenandoah Mountain 100.

Replacing the Sierra-Tahoe 100 of last year’s event is the High Cascades 100 in Oregon. Co-organizer, Ryan O’Dell expresses his excitement over this new move. Oregon will get to have its virgin run on August 7, 2010.

Scheduled to run the same way as 2009, the US National Ultra Endurance Series will close with a bang on Labor day weekend at the Shenandoah Mountain 100 race. This is also where the tiebreaker race will take place based on the best four events score by racers.
